The RC propeller performance under steady and sinusoidally time-varying freestream (stream-wise or longitudinal gust) was investigated in the University of Dayton Low-Speed Wind Tunnel (UD-LSWT) open-jet configuration. propellers were tested at varying incidence angles reduced frequencies. streamwise gust created by actuating shuttering system located test section exit characterized using hot-w...

Conventional measures such as maximum plasma concentration (C max ) and area under the concentration versus time curve (AUC) may be insufficient to fully describe the pharmacokinetic (PK) profile of extended-release (ER) formulations. A complementary measure, the half-value duration (HVD), corresponds to the period of time during a dosing cycle that plasma concentration is at or above half the ...

We propose in this paper a three-dimensional finite element based heat transfer model for a Gallium Nitride-based Heterostructure Field-Effect Transistor (henceforth referred to as GaN HFET). Analyses were carried out to study the distribution of temperature in the HFET under steady state conditions for two different steady-current inputs. Two different substrates for the HFET, sapphire and sil...

Parity-time symmetric lasers have attracted considerable attention lately due to their promising applications and intriguing properties, such as free spectral range doubling and single-mode lasing. In this work we discuss nonlinear modal interactions in these laser systems under steady state conditions, and we demonstrate that several gain clamping scenarios can occur for lasing operation in th...

Based on the thermodynamics involving the lattice expansion due to hydrogen insertion, the interaction between hydrogen atoms and the blocking effect in hydrogen diffusion, we discuss the profiles of hydrogen concentration and self-induced stress, and their interaction in the steady state during hydrogen diffusion across elastic membranes of fcc metals or alloys. Contrary to the conventional vi...

The intrinsic protein fluorescence of the polygalacturonase from Colletotrichium lindemuthianum was exploited in stopped-flow experiments aimed at elucidating the kinetic mechanism for this enzyme. Binding of the polymeric substrate polygalacturonic acid (PGA) essentially produced a triphasic fluorescence profile. There was an initial rapid quench in fluorescence, consistent with the rapid form...

We have investigated numerically the quantum evolution of a δ-like wave-packet in a quenched disordered medium described by a tight-binding Hamiltonian with long-range hopping (band random matrix approach). We have obtained clean data for the scaling properties in time and in the bandwidth b of the packet width˜M and its fluctuations ∆ ˜ M with respect to disorder realizations. We confirm that ...

The Age-Layered Population Structure (ALPS) paradigm is a novel metaheuristic for overcoming premature convergence by running multiple instances of a search algorithm simultaneously. When the ALPS paradigm was first introduced it was combined with a generational Evolutionary Algorithm (EA) and the ALPS-EA was shown to work significantly better than a basic EA. Here we describe a version of ALPS...

This paper investigates the optimal taxation path of a non-renewable resource in the presence of an imperfect substitute renewable resource. We present an optimal growth model and characterize the social optimum and the decentralized equilibrium. We show that the economy gradually reduces the share of non-renewable resource and converges to a steady state in which it uses only the renewable res...
